4.8. The Conditional Operator
The ?: operator is just like an
if .. else statement except that because it is an
operator you can use it within expressions.
Blah, blah, here's an example:
Example 4-6. apples.c
apples = 6;
printf("I have %d apple%s\n", apples, (apples == 1) ? "" : "s");
?: is a ternary
operator in that it takes three values, this is the only ternary
operator C has.
